Bit Studio solely designed and developed an interactive application for Dtac and installed it at Asok BTS Station/Sukhumvit MRT Station. This application detects passers-by and displays gift boxes above their heads. The passers-by can open the box using their hands and the box will explode showing animation of Dtac messages. Our application is not only giving information to Dtac customers in an enjoyable way but also help Dtac to be able to measure the effectiveness of this marketing campaign using the recorded log data from the application.
